ORLADEYO

Following oral administration of berotralstat 150 mg once daily in adults, the geometric mean steady-state C max is 158 ng/mL (range: 110 to 234 ng/mL) and steady-state area under the curve over the dosing interval (AUC tau ) is 2770 ng*hr/mL (range: 1880 to 3790 ng*hr/mL). Following oral administration of berotralstat 110 mg once daily, the geometric mean steady-state C max is 97.8 ng/mL (range: 63 to 235 ng/mL) and steady-state AUC tau is 1600 ng*hr/mL (range: 950 to 4170 ng*hr/mL). Berotralst...

The efficacy of ORLADEYO for the prevention of angioedema attacks in adult and pediatric patients 12 years of age and older with Type I or II HAE was demonstrated in Part 1 of a multicenter, randomized, double-blind, placebo-controlled, parallel-group trial (Trial 1 [NCT3485911]). The trial included 120 adults and pediatric patients 12 to <18 years of age who experienced at least two investigator-confirmed attacks within the first 8 weeks of the run-in period and took at least one dose of study treatment. Patients were randomized into 1 of 3 parallel treatment arms, stratified by baseline atta...

An increase in QTc interval prolongation can occur at dosages higher than the recommended dosage. Additional doses or doses of ORLADEYO higher than the recommended dosage are not recommended. ( 5.1 ) 5.1 Risk of QTc Interval Prolongation with Higher-Than-Recommended Dosages ORLADEYO should not be used for treatment of acute attacks of HAE. Additional doses or doses of ORLADEYO higher than the recommended dosage are not recommended. An increase in QTc interval was observed in adults at dosages hi...
